# [plt-scheme] Critical Question for HTDP ex 11.4.6

Nabeel, I can't speak for the authors but I'll try to answer your question.
First, a link to the problem online (same text as what you copied, but
more compact in email):

The way I read it certainly suggests number 3 above. If the new
definition of numbers presented in the problem is either 20, or
something progressively lower than 20, then the natural recursion that
falls out of that is a tabulation of values from any given n-below-20
up to 20. If you build a template for the solution from the data
definition given in the problem, there should be only one way to solve
it. I hope that helps.
